Abstract: A method and system for maintaining a routing path between a selected workstation (18) and a mobile workstation (36) within a multisegment local area network (10) wherein individual segments (12,14,16) are interconnected by a router device (28,30) and wherein selected segments (14,16) include radio frequency transceivers adapted to provide a wireless communications link with mobile workstations (36). Each time communication is established between a mobile workstation (36) and a selected workstation (18), two routing table entries are established which identify a segment location (14) for the mobile workstation (36) and a segment location (12) for the selected workstation (18) within a routing table (86,84) associated with each router device (28,30). Thereafter, all routing table entries which identify the segment location (14) for the mobile workstation (36) are automatically deleted in response to a termination of communications between the mobile workstation (36) and the radio frequency transceiver. Routing path determination does not require the maintenance of routing path information at each workstation within the multisegment local area network.
